9
After these things I looked, and behold, a great multitude which no one
could number, of all nations, tribes, peoples, and tongues, standing
before the throne and before the Lamb, clothed with white robes, with
palm branches in their hands,

This is not the Church!!

Then one of the elders answered, saying to me, “Who are these arrayed in white robes, and where did they come from?” 14 And I said to him, “Sir,[b] you know.”
So he said to me, “These are the ones who come out of the great tribulation, and washed their robes and made them white in the blood of the Lamb. 15 Therefore they are before the throne of God, and serve Him day and night in His temple. And He who sits on the throne will dwell among them.

NOTE; They serve in the Temple,

The “CHURCH” serve as Priests and Kings Revelation 1:6 (New King James Version)

6and has made us kings[a] and priests to His God and Father, to Him be glory and dominion forever and ever. Amen.
